Assuming that your car is a Yeti (you have not given any details) your other post in which you modify the electrics (radio?) gives the impression that it is used rather than new, from newit would have a three year transferable warranty. The first Yeti's came out around September 2009 so even the "oldest" ones are still covered.
In your other post you are modifying what I assume to be the Bolero /Amunsden, did you modify anything else prior to your latest problem? Was the wiring harness replaced by a dealer and was it done before or after the other faults occoured?
A visit to a dealer with warranty paperwork in hand would be the best course of action.
